Production process of double-point non-woven fusible interlining

Abstract

The invention discloses a production process of a double-point non-woven fusible interlining, which sequentially comprises the following steps of: A) using 43 percent of nylon fibers and 57 percent of polyester fibers by mass as raw materials, laying the raw materials to form a net, heating and hot rolling through a hot mill to enable the nylon fibers and the polyester fibers to be bonded with each other to form a non-woven base fabric; B) softening the non-woven base fabric through silicone oil and conducting inspection; C) cropping after the non-woven base fabric is inspected to be qualified; D) conducting double-point coating fabric feeding after cropping, firstly using a circular screen for primer transfer and then spreading fusible adhesive powder on the primer; E) clearing the fusible adhesive powder which is not combined with the primer by adopting an air blowing and suction method; F) baking through a baking oven, wherein the baking temperature is 167 DEG C and the fabric feeding speed is 36m / min; G) cooling through cooling rolls, wherein deep-well water or tap water chilled by a water chiller is filled into the cooling rolls; and H) conducting final inspection to the cooled double-point non-woven fusible interlining, rolling and containing the double-point non-woven fusible interlining in a box. The production process of the double-point non-woven fusible interlining has the advantages that the production quality is improved, the production energy consumption is reduced, the production efficiency is improved and the production cost is reduced.

Description

【Technical field】 [0001] The invention relates to a production process of a double-point nonwoven hot-melt interlining. 【Background technique】 [0002] The current non-woven interlining has poor softness and poor hand feeling, resulting in low product quality. Paste coating or powder coating is used for bonding, which not only has a large amount of water and slow evaporation, thereby increasing energy consumption, but also the peeling strength of the interlining cloth bonded by this processing method is low, which affects product quality. At the same time, the current interlinings are either only dry-cleaning or water-washable, and it is difficult to take into account both dry-cleaning and water-washing resistance. Moreover, due to the unreasonable setting of process parameters, the vehicle speed is relatively slow during production, which affects production efficiency. Tap water is used for cooling during cooling, which leads to poor cooling effect, prolongs the cooling t...

[0002] The current non-woven interlining has poor softness and poor hand feeling, resulting in low product quality

Paste coating or powder coating is used for bonding, which not only has a large amount of water and slow evaporation, thereby increasing energy consumption, but also the peeling strength of the interlining after bonding by this processing method is low, which affects product quality.

At the same time, the current interlinings are either only dry-cleaning or water-washable, and it is difficult to take into account both dry-cleaning and water-washing resistance.

Moreover, due to the unreasonable setting of process parameters, the speed of production is relatively slow, which affects production efficiency

Tap water is used for cooling, which leads to poor cooling effect and prolongs the cooling time, which further affects production efficiency
